If by "golden ball of sunshine that you want to hug and protect" you actually mean "slightly annoying and transparently trope-y cute, made to sell merchandise" then you are completely correct.

The girls in general of S:G are so built on templates that it's sickening. Most of them are among the best versions of those templates, but they still fit so much into those slots that any characterization they get only becomes a variation on a trope, rather than feeling like actual human beings.
If S:G wasn't so ******* obsessed with creating as many shots as possible at "best girl", i would have liked it a lot more than the 7/10 i personally find it to be.
